Ileoileal intussusception due to an inverted Meckel's diverticulum in a child

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract. In the majority of cases, it is an incidental finding but symp- toms can occur due to haemorrhage, bowel obstruction, infection, perforation and umbilical fistula. We report a case of intussusception due to an inverted MD. A 7-year-old patient presented to the emergency department with vomiting and abdominal pain of 12 hour duration. He also reported rectal bleeding. On physical examination a palpable mass in the right lower quadrant was noted. Hemoglobin level was 13,8 g/dl and white blood cells count was 18.000/µl. Abdominal radi- ography revealed air fluid levels consistent with bowel obstruction. For further evaluation an abdominal ultra- sound examination was performed and revealed the characteristic "target sign" in the right lower quadrant, indicating an intussusception, and free intraperitoneal liquid. Due to clinical deterioration, the patient was taken urgently to the operation room. At laparotomy a section of small bowel was found to be intussuscepted secondary to an invaginating MD (Fig. 1). The MD was resected. The patient was discharged on postoperative day five. Histological examination confirmed the pres- ence of pancreatic ectopic tissue.
